The exponent e of the float in the base given by radix. emin ≤ e ≤ emax. Returns none if the number is not finite.
Decompose the number f in to (s,e) where 0.5 ≤ s < 1.0 and emin ≤ e ≤ emax such that f = s * 2 ^ e.
Decompose in to integer fst and fractional snd parts.
mantissa f returns a number s where 0.5 ≤ s < 1.0 such that there exists an integer e such that f = s * 2 ^ e
remainder of the floating point division operation.
signed remainder of the division operation.
Computes sqrt(x^2 + y^2).
atan2 y x finds the angle anticlockwise from the x-axis to the point [x,y].
Nearest integer not greater than the given value.
Nearest integer not greater in magnitude than the given value.
Round to the nearest integer, rounding away from zero in halfway cases.
